Toward the end of the Twelfth Knesset, the Mapam, Ratz, and Shinui parliamentary groups merged into single parliamentary group. The common denominator among the three was their advocacy of an agreement with the Palestinians on the basis of a territorial compromise, and the establishment of a Palestinian state, civil and human rights, and the separation of religion and state. In February 1997, the three parties united into a single party, though MK Avraham Poraz preferred to stay outside the new party, and formed the Shinui-Center Party parliamentary group. Meretz was headed by Shulamit Aloni (1991-99) and Yossi Sarid (1999-2003). Meretz ran in the elections for the Sixteenth Knesset in a single list with the Democratic Choice and Shahar, and in the course of the Sicteenth Knesset changed its name to "Yahad and the Democratic Choice".
